The topic of my research is programming model support for adaptive Grid applications. We have tied together the concept of Meta-Object Protocol (MOP) with Kahn's Process Network model into a programming model that provides computational and environment reconfiguration within a Grid environment.  Kahn's Process Networks provides us with an expressive, reconfigurable model of computation we will exploit to provide environmental reconfiguration so a metacomputer application may adapt to changes in its environment. A Meta-Object Protocol (MOP) called Enigma helps us to separate the non-functional concerns of adaptation from the application's functional concerns. The Enigma MOP provides Method Intercession at various points of a method lifecycle and Metabehaviour Composition at these points. Enigma is a 100% pure-Java MOP that uses Java Dynamic Proxies for Method Intercession.

The driving application for this research is a Geographical Information System (GIS) called PAGIS which is based upon Distributed Process Networks (DPN).  PAGIS currently exists in prototype form, with public release expected in the near future.  This project is supervised by Andrew Wendelborn. I expect to complete the degree in April, 2002.
